High tech contact lens displays Pixels on the Eyes

Marvel of technology is here. The first version of the contact lens that can directly project pixels on one corner of the contact lens is here. Using these devices we can keep our cell phones and computers right in our eye. Imagine your smart phone display is right in your eye and the micro blue tooth in your ears.

A U.S. and Finnish team is the first to develop real contact lens technology containing an electronic display. The researchers placed the technology into the eyes of rabbits, and initial results show that the animals suffered no ill effects. "This verifies that antennas, radio chips, control circuitry, and micrometer-scale light sources can be integrated into a contact lens and operated on live eyes," says the University of Washington's Babak Praviz, who led the team.

According to the research team, although the first version has only one pixel, a higher resolution lens display is next on the team's agenda. Higher resolution lens displays could one day be used as satellite navigation enhancers that show directional arrows, or flash up texts and emails, and possibly video.
